Passengers rushing to return to South Australia have been left stranded at Adelaide Airport following a change in travel advice.

On Sunday, the state government announced that it would be effectively closing the border to anybody travelling into SA from greater Sydney or a High Community Transmission Zone in NSW.

Those wishing to return to South Australia from greater Sydney were initially given a midnight deadline.

However, the travel advice later changed while some travellers heading to South Australia were mid-flight.

The updated travel rules advised travellers that they would need to quarantine over Christmas upon their arrival in SA.

The change in rules left passengers on Virgin flight VA436 stranded on the tarmac at Adelaide Airport for hours, before being told that they would be forced to self-quarantine for two weeks.

South Australia Police have since clarified that anybody travelling to SA from greater Sydney, Northern Beaches, Central Coast or City of Wollongong after 12:01am on Monday 21st December would need to self-quarantine for 14 days since they last visited one of the affected NSW regions.
